Do I count this as a red flag??

My boyfriend of 5 years and I have recently been having some problems. We’re kind of in between together and not together.. it’s super complicated. And we’ve been like this for a couple of weeks now. His birthday was last month, and we were also in a “meh” place, so I bought him supper and a smoothie, and made him an Oreo cake and got him a card with beef jerky. Things have also been pretty busy so it was hard to go all out this year. I also told him that I’d buy him a pair of shoes next time we went to the city, so that he could pick them out.. anyways.. my birthday is today. And for the past week or two leading up to it, I’ve been super sad and told him that I’m not even going to bother acknowledging it this year. And he said that he already has plans for us for it and how he’s getting me a gift because he wants to and that we’re celebrating. And he said that he got the day off for my birthday. And then, the day before my birthday, he told me that he was going to be coming to sleep with me that night and then he has the day off to spend with me for my birthday. He never came. He worked at the shop all day. He stopped by for 10 minutes in the early afternoon, and said he didn’t have time to stay cause he had to get back to work but that he’d be back later. I ended up texting him not to bother because I knew it wouldn’t happen anyways. He was also ignoring me most of the day. And yes, I know he’s busy working at the shop, but it’s the fact he read my messages no problem, but only answered when it was convenient for him. And especially on my birthday. And any time I say how I feel, he just ignores that too. He said “Happy fucking birthday” at like 3 am and then again a bit later and then in person when he stopped by. I don’t care about getting a gift, but I thought he would’ve put in more effort like I did for him even though we’re not in the best place. Especially cause he tells me he loves me, which is unusual when we’re as bad as we are right now. And I just wanted him to spend time with me at least. And he wouldn’t even come for supper because he “doesn’t like my family now” which is over stupid AF reasons. Am I wrong to be so upset?. I just wanted him to make the day better like I’ve always done for him on his birthdays no matter what. And normally he does for mine too. But lately his new job is his new priority I guess. And I’m stuck on what to do. I just feel so angry and hurt all of the time now lately.
